With your encouragement and patience, let me try to learn and grow in maintaining my desktop.
In visiting the motherboard maker's Support downloads web page, I note there are year 2021 versions of drivers for the following components:-
Realtek HD Audio Driver
Intel INF installation - chipset
Intel SATA Preinstall driver
Intel Graphic Driver
BIOS Driver
As my desktop is procured in 2018 as a assembled machine, I believe all of the above are newer than those in my system.
Which should I install? And how?
There are also other drivers grouped under "Utility", such as App centre & Fast Boot, I think I can ignore those at the moment.
